Reflux cough, i.e. reflux pharyngitis, is mainly caused by reflux esophagitis resulting in the reflux of digestive enzymes and gastric acid in the stomach, which in turn erodes the throat area. It is recommended to go to the hospital ear, nose and throat consultation to clarify the diagnosis, and then follow the doctor’s instructions to apply the acid suppressant, gastric stimulant, mucous membrane protection drugs and other drugs for treatment. 1. Acid suppressants: such as omeprazole, rabeprazole, ranitidine, etc., can inhibit the secretion of gastric acid, and then relieve acid reflux. After using the drug, there may be dizziness, nausea, abdominal pain and other adverse reactions; this drug should be prohibited for those who are allergic to this drug, pregnant and lactating women, infants and young children, and those with severe renal insufficiency. 2. Gastric stimulants: such as domperidone, mosapride, etc., can promote gastric emptying, and thus reduce the gastroduodenal reflux. After using the drug, there may be insomnia, headache, urticaria and other adverse reactions; allergic to drugs, moderate to severe hepatic insufficiency, gastrointestinal bleeding, perforation, and breast cancer, prolactinoma patients and other people, should be prohibited from using this drug. 3. Mucosal protection drugs: such as bismuth, aluminum sulfate, etc., can play a role in protecting esophageal mucosa, neutralizing gastric acid and promoting the recovery of damaged mucosa. After applying the drugs, there may be constipation, abdominal pain, skin rash and other adverse reactions, which must be disposed of by timely medical treatment. The cause of the disease is different, and the method of treatment is different. Patients with reflux pharyngitis need to seek medical attention to identify the cause and follow the doctor’s instructions for treatment.
